Hmm, I have no expertise in this field. I recently read that aging happens, because when cells replicate their DNA a gazillion times, then sometimes they introduce slight inaccuracies or mistakes, which I guess, means tons of tiny chunks of our body will have slightly different DNA from what we got born with…?
From the little I’ve just read about telomeres, it sounds like they help to prevent some of these mistakes. Is that you mean?
